摘　　要：过渡金属硒化物(TMSes)因其独特的结构、较高的理论容量、良好的电化学活性、含量丰富等优点被广泛地应用在电化学能源存储与转化领域中。本文首先综述了TMSes的常见制备工艺,如溶剂(水)热法、电沉积法、模板合成法、气相沉积法等。由于电极材料的形貌、结构、组分、晶面及光电特性等对其电化学性能有很大的影响,TMSes作为电极材料还存在诸多不足之处,如活性位点暴露得不充分;导电性偏低;测试过程中活性组分易团聚、分解等。因此,本文着重介绍了对TMSes的改性研究,包括形貌调控、晶面调控、缺陷构筑、元素掺杂等,揭示了催化材料体系改性对优化和提升催化性能的重要性。最后,对TMSes的未来发展前景和商业化应用进行了总结与展望,以期望TMSes材料在实际生产中得到更广泛的应用。Transition metal selenides(TMSes)have been widely used in the field of electrochemical energy storage and conversion due to their unique structure,high theoretical capacity,good electrochemical activity and abundant content.In this paper,the common preparation techniques of TMSes,such as solvent(water)thermal method,electrodeposition method,template synthesis method,vapor deposition method,etc.,are reviewed.As the morphology,structure,composition,crystal surface and photoelectric characteristics of electrode materials have great influence on their electrochemical performance,TMSes as electrode materials still have many shortcomings,such as inadequate exposure of active sites,low electrical conductivity.The active component is easy to agglomerate and decompose during the test.This paper focuses on the modification of TMSes,including morphology regulation,crystal surface regulation,defect construction,element doping,etc.,revealing the importance of the modification of the catalytic material system to optimize and improve the catalytic performance.Finally,the future development prospect and commercial application of TMSes are summarized and prospected,in order to expect TMSes materials to be more widely used in the actual production.
